Letters Patent No. 87,316,1lcted Februa/ry 23, 1869.

Be'it known that I, ALFRED YOUNG, of the city of Philadelphia, in the State of Pennsylvania, have invented a new and useful Improvement for Preventing the Accidental Discharge of Fire-Arms; and I hereby declare the following a full and exact description of the same, reference being had to the accompanying drawings, which are hereby made part of this specification,

in which- Figure 1 is an inside view of an ordinary gun-lock. Figure 2 is an under view of fig. 1". Figure 3 is the same as fig. 1, but with parts in different position Figure4 is an outside-view of gun-lock.

Figures 5 and 6 are outside views of portions of gunlock.

Figure 7, under view of fig. 6. In these figures, like letters refer to like parts. a a a a is the gun-barrel. bl) b b is the gun-stock. c c c c is the lock-plate. d d d is the hammer. c c e isthe tumbler. f f f is the bridle-piece. g g g is the sere. h h is the trigger. a. t is the cap. is k is the nipple. l Zis the main-spring. m n is the, ordinary half cock and full cock, in the tumbler.

t t is a groove made in plate'c. v c is a sliding piece running in tt. w w isa spring, moving with v v. a; a: is a knob, the stern of which passes loosely through spring w, and is inserted in piece 2:.

z z, pins inserted in outer face of c. -y y,- additional notches in tumbler. p The nature of my invention consists in providing the gun-lock with one or more notches in the tumblers,'additional to those in ordinary locks, into which the sere will fall and prevent the return of 'the hammer upon the cartridge-cap, or nipple; in so placing these notches, or .the first one thereof, that the sere will fall into it when the hammer is raised, just sufiicient to clear the cartridge-cap, or nipple, whereby the hammer will be held in' such position that the hollow cup, or face of the hammer, will cover and protect the cartridge-cap, or nipple. Also, in providingin the lock-plate a sliding piece, which shall confine the sere when in any one of these notches of the tumbler, and also a spring, which in addition to holding this sliding piece inposition, will, by a combination with two pins on the outer face of the lock-plate, fasten the sere, and, through it, theharnmer, so that no force, less than issutficient to break the parts, can release the hammer.

In order to enable. any one skilled in the art to make and use my invention,'I now proceed to describe its construction and operation.

I 'make, in 'the tumbler e, a notch or more, y 3/, so placed that when the hammer is raised, either accidentally or otherwise, suificiently to clear the cap 5, the sere g willfall intothe notch, and prevent the return of the hammer, and, falling into y, will-fasten the hammer-in such position to cause the hammer to become a safety-'cover to the cartridge-cap, or nipple, the hollow face, or cup, being raised just sufficient to clear the cartridge-eager nipple, and at the same time being .Sufiiciently close over and around it to protectvit from outside blows.

These notches are under-cut, to prevent any pull on r the trigger from forcing out the sore, and releasing the hammer. I v v In order to confine the sere in any one of these notches, the slide 2; moves in the groove t t,.passing through the plate a. I

The piece c is on the inside of the lock, the spring w, on the outside, and moves with c. r The knob, or button, at, passes loosely through the spring into the piece 4:.

When not in use, the slide 2: is in position shown in figs. 1, 2, and 4, retained there by pressure of the spring,

and the sere is allowed to play.

When it is desired to fasten in any one of the notches,

the piece '1) is moved forward until it reaches the sere, and prevents it (the sere) from being forced up. This position is shown in figs. 3, 5, 6, and 7.

4 The spring w retains the slide with sufficient power for ordinary purposes, but when desired 'to fasten it for a long time, or beyond the power of accidental discharge, the spring, as seen in fig. 5, is rotated on thestem of. knob at, until one end'oi; the spring w passes over the inclined face of pin 2, and the other comes against the pin 2.

These pins, 2 and z, are made with the top bevelled to one side, as seen in figs. 2 and 7, so the spring to may pass easily over them. The other sides of these pins are under-cut.

The elasticity of the spring keeps it on the surface of the plate 0, so that, if forced backward, the undercut will prevent the spring from being raised, and all the parts, viz, the slide c, sere be firmly locked.

In order to release the sere, it is only necessary to I know that notches have been placed in the tum-' blers of the locks of fire-arms, for the purpose of allow ing the sere to fall therein, and fastening the hammer in position of full cock and half cock; hence I do claim placing notches in the tumbler of locks of fire-' arms, but i What I do claim as my invention, and desire to secure by Letters Patent, is- The sliding piece '0, for confining the sere gin any of the notches of the tumbler, substantially as described.
